Only one choice? If so, FreeBSD. However, I spend a lot of time in a W2K and an XP VM, and on W2K and XP "real" systems. It is probably split 80% BSD, 20% Windows, but when I need Windows, there is no BSD equivalent.

I also have a laptop that's been through a flurry of operating systems -- currently it is running CentOS 4. (The laptop allows me to work from a non-west facing room when the temperature peaks at 103 here every single afternoon.)

I had to vote for Linux since it's my workstation at work. At home, though, I'm still spending a good deal of time on my FreeBSD desktop. On the other hand, my super duper new machine runs Linux, but I haven't moved everything over to there yet.

Mainly OpenBSD and another WinXP multi-booting workstation (tired of emulating) for those apps that require specific OSes, or @!&%#$ flash, or some OO uno packages.

If I need a difficult-to-install-from-sources application, and that binaries are available for, say, WinXP, OSX or FC5, might as well grab a FC5 distro and install it on a slice (or say Oracle on "unbreakable" ).

Basically, spreadsheets, mail, browsers, database, archives on OpenBSD, so that is my desktop I guess.
What does not run on OpenBSD, the lazy I am boots the WinXP,
any*nux beyond that.
What I prefer, or like, does not matters.
Sometimes, getting the job done even needs specifix hardware for specific OSes. So be it!
Fwiw, the explosion engine is obsolete since more than a century. Haven't got much choice either would I need a car.

mac os x as a primary desktop on a mac notebook. pc-bsd on my workstation at work, used to double booted with ubuntu until it crashed for no good reason .

Windows XP at work, Debian at home (like ddekok I can't live without Flash 9 and had problems getting it to work with FreeBSD) - and buying a MacBook Pro rather soon. I think once I get the MacBook my Debian box will be reverted back to FreeBSD and become a headless fileserver.

Opensolaris on an IBM S51 box. Since it is new and doesn't have everything I need yet, I supplement using programs on a Dell Ubuntu box (broken by recent upgrade) or using ProTech 1, with Xfce (my favorite), on my much older Dell laptop. 'Gave M$ the finger quite a while ago.
